EYELET-MAGHINE.

Specification of LettersPatent No. 11,380, dated July 25, 1854,

Be it known that I, Hrs- EN L. LIPMAN, of the city and county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Eyelet-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, making a part thereof,,in which I .Figure 1 represents on an enlargedscale a vertical sectionthroughthe die and counterdie, or follower and anvil block.

structed the eyelet cannot beriveted' from one side, and the consequenceis that after it is partially riveted fromone side, it must be turnedover, and completed. To those who use these machines, this difficulty ofturn ing over the folios, or whatever is to be fastened, in order tocomplete the operation, is obvious, as they are obliged to let go thesheets to be fastened, and they frequently get out of place.

The nature of my invention consists in lower and anvil block, as that aneyelet subjected to their action, shall be equally turned over orriveted at both sides or ends, or nearly so, by a single operationwithout turning over the folios or whatever is to be fastened thereby.By which means I obviate one ofthe most troublesome manipw lationsincident tothe use of this serviceable machine.

To enable others skilled in the art to make and use my invention, I.will proceed to describe the same with reference to the drawings, whlchare on an enlarged scale Fig. 2 represents a similar sect-ion, with thefollower brought down, and the eyelet in place,

i and Fig. 3, represents the form Oftheeyelet of about three to one, forbetter illustrating the invention. 7 1 The. follower A, may be operatedin any of the present known ways, by lever, screw or otherwise. Thepoint B, of the follower, which enters theeyelet, may be also made inthe usual form; but instead of a shoulder where it joins the follower,it is rounded out in a concave form,so as to spread out and turn overthe top of the eyelet. These rounded recesses are seen at a, a, Figs. 1and 2.

The anvil block C, may be of the usual form andprovided with acountersink D, for the point of the follower to enter. A concave grooveor channel 0 surrounds the countersinlnupon which the turned orpartially flanged end (6 Fig. 2) of the eyelet rests. Now, as thefollower is forced down, both the top and bottom of the eyelet, arespread out and turned toward each other, being guided by the concaves a,0, until they are brought down hard against the material to be fastenedby them.

f in Fig. 2 represents the blank eyelet, and f in Fig. '3, the eyeletafter the edges are turned over or riveted; It will be seen that bothends are equally turned over by simply applying the follower once, andon one side only Having thus fully described the nature of my inventionwhat I claim therein as new.

substantially as described.
